Following its first legal case in the Supreme Court, EFL has handled over 200 cases, achieving significant victories in many cases such as the Eppawala Phosphate Case, the Kandalama Hotel Case and the Galle Face Green Case. Two critical cases handled by EFL also include the Air Pollution Case, where EFL convinced Sri Lanka’s government to make vehicle emissions testing mandatory as well as the Case on the Protection of Wetland Ecosystems, which resulted in a halt in the filling of the Muthurajawala Wetland, and initiated the establishment of the National Wetlands Policy. EFL was also an intervenient party in two noteworthy Supreme Court cases; the Maha Oya Sand Mining Case and the Noise Pollution Case, which have both concluded successfully.

As an organisation that started out small, inclusive of seven years of voluntary work, during which EFL operated from the garage of one of its motivated and dedicated founding members, EFL has now become an organisation reputed to be responsible for key breakthroughs in the protection of Sri Lanka’s natural environments, influencing policy and legislature and fostering a sense of environmental stewardship among the citizens of Sri Lanka.
